Correlation between Karnofsky Performance Status Scale and Short-Form Health Survey in patients on maintenance hemodialysis

BACKGROUND: Assessment of quality of life is vital inmonitoring response to various treatment measures. Various instruments, which include both generic and disease-specific instruments, are used in the assessment of health-related quality of life (HRQOL). In this study, we compare two commonly used generic instruments. OBJECTIVES: The objective of this study was to compare two generic instruments, the Karnofsky Performance Status Scale and the SF-36 Health Survey in hemodialysis (HD) patients. The study also aims to find out the association (if any) between HRQOL scores using these two scales and various clinical and biochemical parameters. MATERIALS AND METHODS: Sixty-two maintenance HD patients were recruited after informed consents were obtained. Detailed sociodemographic data was obtained. They were assessed during their regular HD sessions. Serum chemistry (which included serum urea, creatinine, Na+, K+, HCO3-, Ca2+, Po4(2-)), albumin, globulin, total protein and hemoglobin (g/dl) were assessed in all the patients. Adequacy of HD was assessed using second-generation Daugirdais formula. HRQOL was assessed using the Karnofsky and SSF-36 instruments and the scores collated and compared. Data was analyzed using SPSS version 10. RESULTS: Fifty-five patients completed the study (27 males and 28 females, mean age 40.76 +/- 11.05 years and age range of 20-65 years). There was a significant positive correlation between Karnofsky scores and all eight SF-36 domains, but only physical functioning, social functioning and role limitation due to emotional problems maintained the significance on multiple regression analysis. The serum creatinine and hemoglobin postively correlated with physical function, bodily pain, social functioning and Karnofsky scores. Age of the patients correlated negatively with two SF-36 dimensions (physical functioning and role limitation due to physical fitness) and Karnofsky scores. CONCLUSION: This study revealed a good correlation between Karnofsky performance status scale and the short-form (SF36) health survey in this Egyptian population. Age, serum creatinine and hemoglobin significantly influence quality of life in this HD patient population.     

The pattern,clinical characteristics and outcome of ESRD in Ile-Ife,Nigeria: Is there a change in trend?

Background

The prevalence of chronic renal failure and End Stage Renal Disease (ESRD) has remained high worldwide and the epidemiology has changed significantly in the last decade in industrialised countries. While there have been significant improvements in these patient''s outcomes in developed countries, their state and survival is still appalling in developing countries.

Objective

To determine the clinical pattern, presentation and management outcomes in our ESRD population over a 19-year period (1989–2007).

Methods

Seven hundred and sixty patients'' records were reviewed. Data on major causes, clinical presentation, management and survival were retrieved and collated. Data was analysed using SPSS package version 16.

Results

Their ages ranged between 15–90 years (mean ± SD; 39.9±1.67years) with male preponderance (70.3%). Major presenting complaints were body swelling and uraemic symptoms in most studied patients. The predisposing conditions included chronic glomerulonephritis, hypertension, obstructive uropathy and diabetes mellitus. Renal replacement therapy offered included HD in 556(73.2%), Continous Ambulatory Peritoneal Dialysis (CAPD) in only 9(1.2%) patients and renal transplantation in only 7(0.9%). Only 38(6.8%) survived on HD for longer than three months while 7(77.8%) CAPD patients and all transplanted patients survived for between six months and four years (p<0.00001). Median duration of survival after diagnosis for all the patients was 2 weeks (range 0–50 months).

Conclusion

End stage renal disease is still prevalent with chronic glomerulonephritis and hypertension being the common causes. Prognosis is still grave hence subsidized renal replacement therapy and preventive nephrology should be targeted in such underserved populations.     

Doppler ultrasonographic evaluation of celiac and mesenteric arteries in subjects with sickle cell disease

Vasculopathy, as occurring in sickle cell disease (SCD), can affect celiac and mesenteric arteries and result in stenosis, with elevated peak systolic velocity (PSV) on Doppler ultrasonography. In six subjects with confirmed SCD in steady state, routine Doppler ultrasonographic examination discovered features of celiac artery (CA) or superior mesenteric artery (SMA) stenosis with CA PSV >200 cm/s (median = 222.8 cm/s; range = 201.5-427.1 cm/s) and/or SMA PSV >275 cm/s (median 183.2 cm/s; range = 87.8-289.3 cm/s). Among the six subjects, five had elevated soluble P-selectin values (median 72.55 ng/mL), while all six (100%) had elevated cystatin C levels (median 4.15 mg/L). Peripheral oxygen saturation was suboptimal in five subjects. All subjects had low hemoglobin concentration levels (median 8.5 g/dL) while four had elevated white blood cell count. Although vaso-occlusive crises result from microvessel occlusion, these findings at the macrovascular level suggest that SCD patients may also be vulnerable to mesenteric ischemic injury, especially in the setting of anemic heart failure from hemolysis.     

Renal disease in HIV-seropositive patients in Nigeria: an assessment of prevalence, clinical features and risk factors.

In order to determine the pattern of renal disease and risk factors for renal disease in HIV-infected Nigerians, we studied 400 consecutive HIV/AIDS patients (210 males, 190 females) aged between 18 and 65 years (mean +/- SD; 34.6 +/- 9.4 years), and examined renal disease factors attributable to the infection. Diagnosis of renal disease was based on the consistent presence of at least 1+ albuminuria and/or elevated serum creatinine (>132 micromol/l) as well as the absence of other identifiable causes of chronic kidney disease (CKD). We determined socio-demography and clinical findings, as well as full laboratory work-ups including haemogram, CD4+ cell count, serum electrolytes, urea, creatinine, protein, cholesterol and urine analysis. Renal biopsies were taken in 10 patients who had moderate to massive proteinuria and had consented to the procedure. Finally, we compared HIV/AIDS cases with and without renal disease to determine the risk factors for nephropathy. We observed a high prevalence of renal disease (proteinuria and/or elevated serum creatinine), which was present in 152 (38%) of the patients. This subgroup included 74 males and 78 females with a M:F ratio of 1:1. The mean age (+/-SD) was 35.8 (+/-10.01) years. Systolic and/or diastolic hypertension was seen in 13.2% of these patients while the mean (+/- SD) body mass index (BMI) and packed cell volume (PCV) were 18.5 (+/-3.1) kg/m(2) and 25.26 (+/-6.81)%, respectively. The mean (+/-SD) CD4+ count was 246.49 (+/-192.8) cells/microl, while the mean (+/-SD) serum creatinine and 24-h urine protein excretion rates were 210.11 (+/-337.8) micromol/l and 2.57 (+/- 2.42) g/day, respectively. In subjects with and without nephropathy, there were significant differences in age, BMI, serum cholesterol, serum albumin and CD4+ counts, suggesting that these parameters may be risk factors for nephropathy. Histology revealed mainly focal glomerulosclerosis (FGS) with glomerular collapse. We conclude that the prevalence of proteinuria in HIV-seropositive patients is high in Nigeria. Such subjects show an equal male:female distribution, and glomerular histology revealed that a majority of biopsied patients had the collapsing FSGS variant. The risk factors for renal disease included severity of the HIV infection (inferred from the generally low CD4+ count), anaemia, malnutrition and increasing age.
